In the past few weeks I’ve worked more with PowerCLI because I wanted to automate some of the settings and configuration of newly installed ESXi hosts. One of the things was to set the\u00a0Path Selection Policy <\/a>to Round Robin and set iSCSI vmk qDepth to 32.<\/p>\n

So, this script will change the default PSP to RR, change the iscsivmk qDepth and in the end it will enable the iSCSI software adapter.<\/p>\n

I parameterised\u00a0 vCenter and cluster name so it would be easier when running the script, and after that set the arguments for the defaultpsp<\/em>, SATP<\/em> and iscsivmk<\/em> settings. You can change the arguments values based on your storage provider recommendation.<\/p>\n
